Accelerator Oscillator (AC) Backtest The Accelerator Oscillator has been developed by Bill Williams 
 as the development of the Awesome Oscillator. It represents the 
 difference between the Awesome Oscillator and the 5-period moving 
 average, and as such it shows the speed of change of the Awesome 
 Oscillator, which can be useful to find trend reversals before the 
 Awesome Oscillator does.

Bill Williams. Awesome Oscillator (AO) Backtest    This indicator is based on Bill Williams` recommendations from his book 
    "New Trading Dimensions". We recommend this book to you as most useful reading.
    The wisdom, technical expertise, and skillful teaching style of Williams make 
    it a truly revolutionary-level source. A must-have new book for stock and 
    commodity traders.
    The 1st 2 chapters are somewhat of ramble where the author describes the 
    "metaphysics" of trading. Still some good ideas are offered. The book references 
    chaos theory, and leaves it up to the reader to believe whether "supercomputers" 
    were used in formulating the various trading methods (the author wants to come across 
    as an applied mathemetician, but he sure looks like a stock trader). There isn't any 
    obvious connection with Chaos Theory - despite of the weak link between the title and 
    content, the trading methodologies do work. Most readers think the author's systems to 
    be a perfect filter and trigger for a short term trading system. He states a goal of 
    10%/month, but when these filters & axioms are correctly combined with a good momentum 
    system, much more is a probable result.
    There's better written & more informative books out there for less money, but this author 
    does have the "Holy Grail" of stock trading. A set of filters, axioms, and methods which are 
    the "missing link" for any trading system which is based upon conventional indicators.
